A 60GHz Class F-E Power VCO with Vector-Modulator Feedback in 65nm CMOS Technology
Résumé
A structure of a millimeter-wave transmitter architecture based on a Power VCO principle including a vector-modulator as a feedback loop solution is presented. This structure is dedicated to the V-band around 60 GHz. The Power VCO is designed in 65nm CMOS technology of STMicroelectronics. It is composed of a 2 stages class F-E power amplifier (PA) inserted in a loop to fulfill the oscillation conditions. The simulation results shows 9.5dBm output power at 60 GHz, a phase noise of -91.6dBc/Hz at 1MHz offset, for a consumption of 157mW.
